I am currently testing Launchbar to switch from Alfred and ported a few of my workflows. One thing I have some issues with though is metadata search.

DEVONthink exposes it's index to spotlight with a bunch of metadata files like this:

In Alfred, I can point it to the metadata folder and set up a advanced search by specifying the exact files I want it to search, this is then making the actual item names within DEVONthink searchable in alfred:

I set up a new Launchbar index item and pointed it to the same folder, ticked "Search File Package Contents" and limited it to only DEVONthink metadata files, but the search is still completely useless.

How would I go on adding support for this? Can I do this built in or do I have to write a new action?
